发明名称 SUBSEA WELL INTERVENTION SYSTEMS AND METHODS
摘要 Systems and methods for well intervention include a lower riser package (LRP), and an emergency disconnect package (EDP). The LRP includes a tree connector, a connector and seal stab adapter (CSSA), and a LRP body; the tree connector has a profile for mating to the CSSA. The CSSA has at least one seal stab assembly for fluidly connecting with a subsea tree. The body of the LRP includes one or more sealing elements that are capable of sealing upon command, an integral annulus with an annulus isolation valve, an upper hub profile compatible with the EDP, and a lower flange profile that mates with the CSSA. The EDP includes a quick disconnect connector, at least one annulus isolation valve, and one or more sealing elements that are capable of sealing upon command. In some embodiments, an internal tie-back tool connects to the EDP via an EDP internal tie-back profile.
